We use DDR_Stress_Tester_V1.0.3_UART1_for_SDboot&JTAG on i.MX6Quad original board.
We use the initialization file which we made in i.Mx6DQSDL DDR3 Script Aid.
When the DDR frequency is set to 400MHz, the DQS gating calibration succeeds.
However, when the DDR frequency is set to 528MHz, an error such as the following occurs.
Would you like to run the DQS gating, read/write delay calibration? (y/n)
Starting DQS gating calibration...
. . . . . . . . . . . . . . ERROR FOUND, we can't get suitable value !!!!
dram test fails for all values.
We doubt an initialization file in i.Mx6DQSDL DDR3 Script Aid.
We checked a parameter of Register Configuration, but do not understand the cause of this error.
May I have advice?
